215 * dirty hack, we set LDLM_FL_LVB_READY only after we've done the LVB poop.
216 * this is only needed on LOV/OSC now, where LVB is actually used and
217 * callers must set it in input flags.
219 * The proper fix is to do the granting inside of the completion AST,
220 * which can be replaced with a LVB-aware wrapping function for OSC locks.
